COMBINED oomrscnnw AND oonx BORER.

Application'filed Apr-i129, 1927. Serial No. 187,548.

. Thisinvention relates to a combined corkscrew and corkborer andit comprises a corkscrew'having a helical screw portion or the like further provided with a sheath, advantageouslycylindrical, such as a tube providedwith a cuttingedge, disposed about said screw portion and adaptedto bore a hole in a cork and to retain and withdraw the bored out portion of the cork.

Manyof the proprietary preparations such as astringents, hair tonics, dandrufi removers and the like are'bottled inbottles, provided with .cork stoppers, In dispensing thecontents of bottles containing such preparations, there' is a need: for an exceedinglyinexpen sive, easily constructed corkscrewnot only adapted' to' Withdraw the cork, which is usually firmly inserted in the :mouth of the bottleeduring bottling, but to also .bore a hole in the cork whereby the contents of the bottle may be shaken out inmuch the same way as the contents of bay rum'bottles is dispensed. Such, bottles usually have a cork stopper of special construction provided with an arrangement whereby the inverted shaking of the bottle dispenses asmall volume of the contents at a time.

I have 'found' that the contents of a bottle may be shaken out through an ordinary cork in the mouthof the bottle if the cork is providedwith a hole of small diameter, say threesixteenthsof an, inch. 7 I It is therefore an object of. this invention to' devise a corkscrew which is adapted to "bore a hole in a cork for the purposes above mentioned. It isa further object of this invention to devisea combined corkscrew and corkborer easily assembled'at but little cost so as' to makeit readily distributable gratis with bottled preparations of the char- 1 acter described and the like. YInthe accompanying drawings I have illustrated one mode of applying my invention,.it being understood however that I some wish to be limited to the precise form of construction shown.

7 In the drawings: Figure 1 shows in perspective a part of a bottle provided with a cork and illustrating the position ofthe combined corkscrew 1 and corkborer when in use.

Figure 2' is a sectional view through the neck of a bottle showing a corktherein with the corkscrew and corkborerin place. "Figure 3 is a top section taken along the line 33 of Figure 2 and Figure 4 illustrates an advantageous method of forming the corkscrew and corkborer. y

In the drawings, likenumerals refer to like parts. I

Referringmore particularly to Figure'2, 8 represents the neck of a bottle having a cork 5 in the mouth thereof. The corkscrew andvcorkborer is indicated by the elements 1, 2, 3 and 4. It comprises a corkscrew having a ring or handle 1 and a screwportion 2, shown in the form of a helix, adapted to screw into the cork. Disposed about the screw 2 isa cylindrical sheath or tubular cutter 3 fastened to the ring 1 by flared out portions 4 bent around and fastened tothe ring 1. The sheath or tube, which acts as a cork borer, has its lower end 7 beveled or sharpened so that a cutting edge is formed. The lower end advantageously terminates slightly above the extremity of the screw 2 so that in use, the screw 2 enters the cork first. However, the lower end of the sheath or tubular cutter 3 may .terminate above or below theend of the screw.

The' sheath or tubular cutter should -fit rather closely about the screw so that its diameter is not unduly great. The drawing,

for the sake of clearness, shows the corkboring sheath or tube as having a diameter almost twice as great as the screw. Actually, the internal; diameter of the sheath need only be slightly greater than the diameter of the screw so that the sheath or tube-is slightly spacedfrom the screw. 1

' Figure '3, a cross section taken along 3-3 of Figure 2 shows the neck of the bottle,

the cork, the screw 2 and the sheath or tube as a top view. 7

An advantageous way of making the combined corkscrew and corkborer is illustrated in Figure t. An ordinary wire corkscrew 1, 2, is provided in any known manner., A piece of tubing 3 is cut of thedesired length. Its lower end is beveled to form a cutting edge 7 as shown. The upper end of the tube or sheath is slit for a way. at 9 and the cut or slit endis then flared out. The sheath is slipped over the screw, the flared ends bent about i and around the ring 1.

Other fastening means. may, of course, be employed. i

In use, the assembled combined corkscrew and corkborer screwed into thecork, the

cork being advantageously retained in the mouth of the bottle during the operation.

access to the contents of the bottle.

The sheath or tubular cutter 3 is so proportioned to; the cork that it is at least as long as the cork so that it can bore a hole all the way through the cork. As the screw penet-rates the cork, the corkborer readily cuts a hole in the cork. After the cork is bored through, the corkscrew is withdrawn to gain The contents may be readily shaken out through the hole in the cork in small portions.

Thebored out part 6 of the cork is securely retained within the sheath, the screw coacting with the sheath or tube to hold the bored portion within the sheath. The screw greatly facilitates boring the hole since it acts to draw the boring sheath into the cork. Furthermore, in my construction, small particles of cork do not breakoll to subsequently fall into the bottle and contaminate the'contents.

After a suihcient quantity of the contents of the bottle has been shaken out, the corkscrew and corkborer is reinserted in the hole in the cork, acting in this way as a stopper. This is one of the advantages of providing a cutter adapted to retain the bored out portion of the cork. If it is desired to withdraw the cork as a whole, the corkscrew and corkborer is inserted in the hole and wobbled a little to loosen the cork. If it is not desired to bore a hole through the cork, the corkscrewand corkborer is screwed into the cork but part way just as an ordinary corkscrew is manipulated.

The implement may be made of any suitable material. I have found brass an advantageous metal to use.

Having thus described my invention, what I claim is: p

1. A combined corkscrew and corkborer having a;helical screw adapted to. screw into a cork and an annular sheath disposed about said screw, said sheath having a lower cutting edge and the upper end of said sheath being firmly fastened to the corkscrew by means of flared out portions of the sheath.

2.. .A combined corkscrew and corkborer comprising a helical screw fastened to a holding ring, a sheath disposed about'said screw. said sheath being adapted to cut a hole in a cork, and means for firmly fastening said sheath to said ring, said means comprising flared out portions forming a continuation of the sheath,said flared out portions being wrapped about the ring and secured. thereto.

3 A combined corkscrew and corkborer comprising a corkscrew and corkboring means carried by the corkscrew disposed in fixed relation thereto and adapted to retain and withdraw the bored out portion of the cork.
